I was unable to find a thread that addressed this, so hopefully I'm not missing something obvious.

Somehow, after installing the Vista Inspirat BricoPack, my wallpaper was shifted 120 pixels to the right, and no matter what I do, I cannot seem to figure out why.

Here's a screenshot illustrating the problem, using a default background that came with the pack. It is set to "stretch" to the screen size:

You may or may not be able to tell from this screencap, but the image is still its original size, just shifted 120 pixels to the side, going offscreen.

I should also note that I typically use AWC to control my desktop background, though I don't think it has any bearing on the current issue.

EDIT: I've managed to create a temporary fix by changing my desktop background settings to "Center" the image, then rotating the desktop 90 degrees and then reversing the rotation. Really awful, but I'm hoping to get some help here for a more permanent kind of fix.

Hi Desh !

I never saw this problem before, it`s new to me - maybe try another freeware to change your wallpapers  

I've figured out that its definitely not AWC doing it - I disabled it and restarted a few times, changing settings in-between.

What happens when you change the wallpaper now ? The same problem ?

Try any other wallpaper-freeware, maybe something messed up parts of your registry ...
